FRUIT JUI CE EXTRACTOR Filed May 22, 1934 James L.MAULL Patentecl Feb.12, 1935 UNITED STATES PATENT OFFICE 6 Clams.

Ths inventon relates to a. ruit juice extractor especially adapted forctrus fruts. It is an improvement upon the nvention desorbed in myPatent 1,922,773, granted August 15, 1933.

One of the objects of the hventon s to provide an extraotor of the cupand tube type in Which the portonof the tube which is nsertable into thefruit s adjustable nlength to suit different sized fruit, so that thedevce is equally adaptable to an orange as to a grapefrut.

Another object of the nvention is the provison of means for locking thetube in various positons of adjustment with respect to the cup.

A further object of the nventonis to provide anextractor of the typedescribed. in whch the tube s provded wth longitudinal corrugatonsntersecting the tra'nsverse plane of the cup in all positons ofadjustment of the tube, whereby the upper parts of the corrugatonsextend into the frut forming free passages for the discharge of thejuice, Whle the lower parts open directly into the glass or other vesselover which the cup may be postoned.

Another object of the inventon is the substtuton in the tube ofcorrugatons instead. of slots as in the devce of my patent hereinabovereferred to, to faciltate cleaning, and for a. 1ike purpose, the ends ofthe tube are unconstricted.

Other objects of the invention will appear as the following descriptonof a, preferred and. practcal embodiment thereof proceeds.

In the drawing which accompanies and forms a part of the followingspecficaton and throughout the several figures of whch the samecharacters of reference have been employed to designate dentical parts:

Figure 1 is a longtudnal section through my mproved juce extractorillustrating its use in connection with a. milk bottle;

Figure 2 s a. side elevation;

Figure 3 is a bottom plan vew;

Figure 4 is a. perspectve view of the tube; and

Figure 5 is a cross sectonthrough the tube.

Referring now in detail to the several figures the numeral 1 representsthe tubular element of the juce extractor which is telescopicallymounted, with frictional fit in the lower s1eeve porton 2 of the cup 3.The tube 1 is formed. at ts upper end. Wth a knife edge 4 serrated atntervals by the indentations 5. The tube 1 at some slght distance belowits upper end. s provided wth a circumferental series of longtudinalcorrugatons 6 pressed. in from the surface of the tube, and in the actof pressing the material is incidentally drawn in so that the dameter ofthe tube in the zone of the corrugations is somewhat less than itsdiameter adjaLcent the upper end. This dfierence in. dameter s noi;materal to the functonng of the invention, nor is it a necessa.rylmitaton of the scope of the inventon. V 5

Within the tube 1 and. at a point abovethe zone of c0rr1igatons is abafle or partiton 7 preferably eentrally perforatedas at 8. Thspartition s secured withn the tubel by resting upon the upper ends ofthe corrugatons and haying 10 the metal slightly struck in as at 9 abovethe edge of the partton 7. The cup 3 is provided. with the usual flange10 adapting it to rest over a glass or cup wthout risk of its slippngoff, and Wth a funnel-like annular channel 11 surrounding the 1 tube 1when the'latter s in place. Said tube is freely slidable within the cup3 and may be secured in any postion of longtudinal adjustment by meansof a. vertcal series of indents 12 whch may be selectvely engaged by a.tit 13 struck in 20 from the side of the cup 3. In making theadjustment, the tube 1 is pushed. ether up or down to the approximatedesired height and then slightly rotated to bring the tt into theappropriate one of the indents 12. f 5

The telescopio relation of the tube and. cup permits regulaton of thelength of that partkof the tube whch projects above the cup and which sadapted to be inserted in the fruit, so as to sut the devce to theextracton of juce from frut of 30 any sze. For example, if an orange isto be dejuced, the tube 1 is pushed down to the lowermost heght providedby the series of indents 12 and then looked in position. If it is a.grapefruit, the tube s raised to an adjustment provided by 35 one of theother indents.

The knfe edge 4 at the top of the tube cuts through'the membranesurrounding the sectons of the citrus fruit and sets the-juice free. Asthe tube s pushed up into the pul'p, the rag and 40 seeds are forcedback by the partition 7, a.ny juce that niay have been entrained wth therag es;- capng through the perforation 8.

It Will be understood that the longtudnal seres of cofiugations 6ntersectthe plane of the 45 cup regardless of its poston of adjustment,thai: is to say, whle the upper ends of the corrugatons extend above thecup, the lower ends rea,ch below it. The corrugations thus formcontinuous passages leadirg into the body of the fru t ai; one end 50and directed into the bottle or other receptacle at the other end sothat upon squeezing the orange or grapefruit With the hand, the juce sfreely discharged. Such juce as ma.y 1eak' around the hole whch theknife edge 4 cuts into 5
